'Campaign' in the Bible

Joshua conquered all of these kings and their territories in one campaign, because the LORD God of Israel fought for Israel.

Joshua fought an extended campaign against all those kings.

The LORD said, "They'll hand you over." David and his men, about 600 strong, got up and left Keilah. They moved around wherever they could go. Saul was advised that David had escaped from Keilah, so he stopped the campaign.

Then Achish summoned David and told him, "As surely as the LORD lives, you are trustworthy, and it seems good to me for you to campaign with me as part of the army. Indeed, I've not found any evil in you from the time you came to me until now. But the leaders don't approve of you.

During David's military campaign against Edom, when his army commander Joab had gone out to bury the dead, he killed every male in Edom.
